CCL23 (MPIF-1, CK8, SCYA23), a member of the CC chemokine family, was originally isolated from a human aortic endothelial cell library and from the human monocytic cell line THP-1. It is most closely related to MIP-1 and interacts with its receptor CCR1, which is expressed on monocytes, dendritic cells, lymphocytes, and endothelial cells. Functionally, CCL23 has chemotactic activity for monocytes, DC, lymphocytes, neutrophils, osteoclast precursor cells, and endothelial cells. In contrast, CCL23 reduces the proliferation of progenitor cells giving rise to granulocyte and monocyte lineages, whereas it enhances angiogenesis of endothelial cells
<1.0 EU/μg of recombinant protein as determined by the LAL method.
Biological Activity Comment
Determined by its ability to chemoattract human T cells using a concentration range of 2-40 ng/mL.
Weight
11.0 kDa
Description
A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Format
Lyophilized PowderRecombinant CCL23 was lyophilized from a 0.2 μm filtered 20 mM PB, 100 mM NaCl solution pH 7.5.
Purity
>95% as determined by SDS-PAGE
Storage
The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
